Randomized Controlled Trial
Impact of Advanced Patient Counseling Using a Training Device and Smartphone Application on Asthma Control.
Pressurized metered-dose inhalers (pMDIs) are among the most commonly used aerosol delivery devices. Poor lung deposition from a pMDI is often a result of incorrect inhalation technique. The aim of this study was to compare the impact of combining a newly released training device with a smartphone application (advanced counseling) in asthma control to the impact of traditional verbal training. ⋯ The use of a training device with a smartphone application in conjunction with traditional verbal counseling in pMDI technique resulted in significant improvements in asthma control compared to traditional verbal counseling in pMDI technique alone.
